RV / Camper Mounting bracket for battery monitor

thingiverse

I crafted this compact battery monitoring bracket to track my RV's battery voltages with precision. It boasts a 12V and a 24V display that can be toggled on and off independently. Key components are readily available at Banggood: Switches: I sourced 5pcs of 12mm latching push-button switches from https://www.banggood.com/5pcs-12V-12mm-OnOff-Latching-Push-Button-Switch-Red-Green-p-1065108.html?rmmds=myorder&cur_warehouse=CN, perfect for my needs. Voltage display: The 0.28-Inch 2.5V-30V Mini Digital Voltmeter from https://www.banggood.com/0_28-Inch-2_5V-30V-Mini-Digital-Voltmeter-p-974258.html?cur_warehouse=CN fit the bill. A bit of filing may be required to snugly fit the voltage meters, but I wanted a secure fit. To keep everything in place, I hot-glued all components to the back. As it turns out, there's no need for locking rings on the switches; they wouldn't fit the frame anyway.
